DEMOUN TABLE RIM.

Be it known that I, ALBERT'L. ANDERSON, a citizen of the United States, residing at Spokane, in Spokane county and State of ened with facility, and which also permits the rim to be appliedto the felly or other part of the wheel with convenience, and without the necessity of skilled assistance. the invention contemplates a construction involving a novel form of hinge joint between the long and shorter section of the demountable rim, together with other improved features of construction and combinations and arrangements of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings illustrated one complete example physical embodiment of devised for the practical application of the principles of my invention, and while a full disclosure is illustrated, it will be understood that colorable changes and alterations may be made in thestructure without departing from the spirit of my invention and scope of my appended claims.

Figure 1 is a view showing in full lines the demountable, sectional, hinged rim, detached, as to one portion, from the tire that is shown by dotted lines.

ig. 2 is an enlarged, detail, plan view at the hinge joint between the sections of the mm.

Fig. 3 is a transverse sectional view at the hingejoint on line 3-3 of Fig. 2.

Fig. 4 is a central longitudinal view at the fastened joint of the free ends of the rim sections. r

Fig. 5 is a plan view showing the fastened ends of the joint of Fig. 4.

To. illustrate the relation of parts I have indicated a conventional automobile wheel tire by dotted lines 1, to which the demount- Specification of Letters Patent.

able rim is attached. The rim is made up of sections, the longer one being inner periphery of the tire, as indicated in r 1 gagernent with the heads at the side walls of equidistant from of the complete parallel circumbetween them an central of the rim and tne tire as usual. Spaced the inner peripheral center rim are arranged a pair of ferential ribs 5 forming annular groove 5 designed to co-act made for the inflation of the inner tube of the pneumatic tire by the shown attached to the long section 2 in Fig. 1. One of the meritorious and essential features of the device resides in the hinge joint designated as a whole the numeral 1, and it will be noted in the drawings that a pair of alined, transverse sleeves 6 and 7, overlap the hinge joint and extend between the two ribs 5 as in Fig. 2. These alined struction enabling the manipulation of the 'wheel parts with facility and rapidity in demounting the rim or p ace.

The free ends of the rim sections are provided with complementary beveled edges 10 and 11 that overlap as in Fig. 4 permitting the section 3 to be readily withdrawn, as in Fig. 1, from the longer section, and with equal convenience permitting the closure of the short section into place.

To provide locking means for the free ends of the sections I employ a pair of loops l2 and 13, the former a keeper and the latin attaching it in thlatchimaybe locked in ter aguide or bearing loop inner circumferentialcenter of the rim between the ribs 5 as disclosed in Fig. 5.

The operation of the slide plate 14; w ll be obvious, and in order that cure the free ends of the sections, said latch is provided with a central slot l5 near its rear end, and a spring pawl 16 is pivoted in latch, the operating end its forward A end slipped I latch is the walls of the slot and 'carriedby the i of the pawl being designed to engage one of the teeth or corrugations' 17 provided therefor on the face of the section 2. Thus it will be apparent ,that after the overlapping ends of the sections have beenbrought to proper position,

the latch carried by the section 2 may have through the loop 12 as shown .1n Fig. 5, and

:which is held out of engagement while the being slipped home, .'s released to to lock the latch against engage the teeth 17,

Frornthe above description taken in connection with drawings. it is obvlous that for the slide 7 latch 14:. Theseloops are integralwith their v respective rim sections and are stamped out or struck .up therefrom and located in the latch or metal position to sei the pawl '16,

have provided an improved and novel form of demountable rim which fulfils the objects and purposes set forth and performs its functions in a comparatively ,7 perfect mannengp Having thus fully tion, what I claim as new secure by Letters Patent is- 1.
